Three major cities in China have suspended trade in live poultry while the rest of the country remains on edge after 18 cases of H7N9 in humans have been reported in East China.

On Saturday, Shanghai, Nanjing and Hangzhou placed bans on the sale and trade of live poultry, city officials said. Two new cases of the bird-flu strain were reported in Shanghai, bringing the total of confirmed cases in the city to eight as of 7 pm, and the number nationwide to 18. Elsewhere, six cases were reported in Jiangsu province, three in Zhejiang and one in Anhui.

Chinese health authorities said that all confirmed cases involved diseased poultry and that there has been no sign of human-to-human transmission.

On Saturday, Shanghai banned live poultry from other parts of the country from entering the city and began mass slaughter of birds after H7N9 was found in pigeon samples from a farm-product market in the city's Songjiang district.
